Fotofly v0.1 available for Download on Codeplex
After several years of evolving my photo metadata code I’m finally ready to put it online. Being the nice corporate citizen that I am, I’m using CodePlex and you can find Fotofly here for download. My somewhat lofty description of the project is: “A comprehensive C# library for reading, manipulating and writing metadata stored in jpg photos using WPF and the Windows Imaging Component. Includes support for Windows Live Photo Gallery People Tags, GPS Coordinates and most EXIF, XMP & IPTC properties.” Hopefully I’ll get lots of downloads and feedback to help improve it further.    
Basic Editing of Photo Metadata Using Windows Imaging Component
In my previous posts I’ve provided examples on using Windows Imaging Component to Read & Write jpg metadata. In this post I’ll explain how to use ContainsQuery , GetQuery , SetQuery and RemoveQuery . As an added bonus I’m going to use the IPTC address fields as my example. Whilst BitmapMetadata does provide some standard properties like Subject and Title, it is far from comprehensive. In order to get at the other data you have to provide the right query.  
Writing Photo Metadata Using Windows Imaging Component
In this blog I’m going to build on my previous posting on Reading Metadata and explain how to write metadata stored in a jpg file using Windows Imaging Component . You can find all my blogs on Windows Imaging Component here . If you want to change any of the metadata, the first thing you have to do is make sure there’s room for your changes. This is done by adding padding to the metadata. If you don’t do this, I guess it’s possible to remove data or change it to the exact same size but you can’t add new data. The general recommendation appears to be around 5k, so I normally use 5120.  
Reading Photo Metadata Using Windows Imaging Component
I still see a lot of questions on the Internet and at work on how to read (& write) metadata in Photos. There are plenty of examples out there but they all appear to have some pitfalls. To be quite honest, the code I’ve been using for a number of years now is mature enough that it solves almost all the problems I’ve seen. This blog is the first in a series that document how to read (this blog), write and manipulate photo metadata.
